Brillant Korsar ® park shrub rose – pharmaROSA® NEONATAL rooted cutting
Reliability in disease resistance, upright-bushy structure and strong winter hardiness make Brillant Korsar ® a robust choice for UK nursery systems needing predictable, low-intervention stock for flower beds, hedging and rose arches. This own-root pharmaROSA® NEONATAL material supports scalable production of standard container lines in 2–3 L, with a bush-trained, compact release form that integrates smoothly into professional propagation and scheduling workflows. Semi-double, cup-shaped, clustered blooms in intense orange-red deliver sustained ornamental impact through a well-repeating second flush, while good colour retention maintains saleable presentation across the bench. The development arc from roots in year one through shoot build-up in year two to full ornamental value in year three aligns well with nursery planning for resilient, long-lived landscape and collection plantings in climates that handle winter cold and frequent strong winds. Partially pollinator-friendly flowers and bright red, spherical hips with ornamental value further support thematic collections and public-realm installations where ecological function and visual continuity both matter.

| Growth and structural characteristics |
Upright, bushy habit with slightly arching shoots, forming dense, glossy dark green foliage; reaches approximately 120–180 cm height and 80–130 cm spread, with moderate prickliness suited to structural planting. |
| Flower morphology |
Semi-double, cup-shaped flowers with 13–25 petals, generally carried in clusters; large bloom size in the 2.75–3.95 inch range, repeating well with a generous second flush across the season under appropriate management. |

Uniform intense orange-red petals (RHS 34A outer, 40A inner); colour holds well with only slight fading to coral red in strong sun, maintaining a warm tone from deep dark red buds through full bloom and gradual lightening at petal edges. |
| Fragrance and aroma |
Very faint, barely noticeable scent with a soft, rosy character; fragrance is present but not a dominant feature, allowing emphasis on colour, health and structure in professional production and marketing. |
| Hip characteristics |
Moderately abundant spherical hips, approximately 8–13 mm diameter, bright red and visually distinct; hips add seasonal interest in autumn and early winter, with ornamental value in landscape and collection settings. |
| Resistance and winter hardiness |
Good tolerance of heat with irrigation support in prolonged drought; fully hardy to approximately -26 to -23 °C (RHS H7, Swedish Zone 4, USDA 5b); resistant to powdery mildew, black spot and rust under typical nursery and garden conditions. |
| Horticultural recommendations |
Suited for flower beds, specimen use, hedges, pergolas and rose arches; low maintenance with strong disease resistance, though weak self-cleaning may require deadheading; recommended as bush-trained, compact plants in standard 2–3 L containers. |
